We are proud to welcome Keuring Service Nederland (KSN) as an independent part of Sansidor! KSN provides a wide range of electrical tests and inspections for electrical installations, solar panels and tools, in addition to checking extinguishing agents and fall protection. With this acquisition, we are significantly expanding our national presence and doubling the share of electrical inspections within our growing portfolio.

Sansidor is the umbrella organization of a group of independent companies. Usually inspection and advice companies focused on healthy, safe & sustainable buildings and spaces in which people reside. The pillars of the service are aimed at: Water safety, air research, fire prevention, infection prevention, gas, oil, bio- and climate installation inspections and electrical inspections.

The takeover of KSN fits perfectly within this last segment. The addition of KSN gives us the opportunity to offer our customers an even broader base and to add capacity to conduct electrical inspections. Think about:

  • Electrical installations (NEN 1010, various SCIOS Scopes)
  • Solar panels
  • Power tools and resources (NEN 3140)
  • Fire extinguishers and fall protection
  • Thermography scans

Now that KSN has become part of Sansidor, customers of all Sansidor companies can benefit from the knowledge and expertise of this great company. This fits within Sansidor’s Buy & Build Together strategy, says Udo Waltman, director of Sansidor: “We are very pleased to welcome KSN and its specialists. We had a great need for a second strong brand for electrical inspections and the geographical spread of these activities. That is perfectly filled in this way. The innovative approach to preventing barn fires also appeals to us. More on this soon.”

Karlo Rosing will remain closely involved in the company and, with Sansidor’s support, will be able to focus more on the professional field in due course. Rosing: “In the search for a party that is good for colleagues; appreciate our specialism; and gives me the space to remain involved and in the long run to focus more on the professional specialism, I have found a good partner in Sansidor. The personal contact and no-nonsense approach also appealed to me and fits well with our company, the colleagues and – of course important – with our clients.”

Sansidor continues to grow in this way, further developing within the Testing, Inspecting & Certification industry. In the coming period, Sansidor also hopes to add new players to the team of specialist companies from all over the Netherlands.
